Dear Mr Bradley,
Thank you for your correspondence to the Mayor of 6 January 2009, which has been passed to me for response.
I apologise for the considerable delay in responding to you however, we have continued to receive a huge response from the public on matters raised by the Mayor (particularly regarding crime). This has resulted in a substantial increase in volume of correspondence received and meant that it has not been possible to reply to all the letters and emails as promptly as usual.
I trust that the issues raised in your letter have now been resolved, you maybe interested to know that the Mayor chairs the Metropolitan Police Authority which means that if you issue sin relation to policing they can answered directed by email their details are as follows: firstname.lastname@example.org.
Once again, thank you for contacting the Mayor and I apologise for the delay in responding to you.
